CVE-2026-23346

CVE-2026-23346 affects the Linux kernel (arm64) in the ioremap_prot pathway. The root cause is that ioremap_prot() may extract non-address bits from a user mapping’s pgprot_t (including permissions) and generate a new user mapping, which can be accessed by the kernel when PAN is enabled. This can...
